New Scientist reports that researchers at University of Southampton, UK, have developed a tiny electric generator that converts environmental vibrations into stored electrical energy.
The generator converts 30% of environmental kinetic energy into electrical power, and could keep all sorts of low-power devices running without batteries – particularly when alternatives like solar power are not an option.Steve Beeby, an engineer at the University of Southampton, UK, led development of the device. He says it could power devices attached to bridges, large buildings and other structures that experience vibration.
